I'd agree with Murano, rather than Chinese made for Murano, as the canes look to be a little before the Chinese influx. But I could be wrong....
As for what one sees in a cane, many people have shown that our brains are hard-wired to recognise faces, and interpret random shapes of light and shade in that way - so if the dark and light blobs happen to be positioned like features of a face, we see a face. So who knows whether it is intentional, or serendipity in your paperweight.
From time to time collectors go on about millefiori canes that are shaped like 'a seagull', or a 'dancer' or some other fanciful interpretation, when all that has happened is that a regular star shape has been distorted in manufacture. Again - you see what you want to see: it is not a case of 'right or wrong'.
